GASOLINE RESERVE SUPPLY.

I Application filed July 14, 1922. Serial No. 574,971

To all whom it may concern.

Be it known that I, JOSEPH L. SoHMiD LING, a citizen of the United States, and

resident of Milwaukee, in the county of Milwaukee and State of -Wisconsin, have invented new and useful Improvements in Gasoline Reserve Supply, of which the following is a description, reference being had to the accompanyingdrawings, which are a part of this specification.

This invention relates to a reserve supply attachment for gasoline tanks and more particularly to gasoline'tanks used on auto,- mobiles.

Automobile owners often fail to, note the supply of gasoline contained in the tank and exhaust the supply a distance from places where the same can be replenished.

It is therefore the particular object of this invention. to provide a device adapted to be connected between the tank and carbureter which will malntain a reserve sup:

ply of fuel in the gasoline tank, which re serve supply, in order to be made available must be connected to the fuel supply pipe by manipulating the valve forming a part of this invention, thereby indicating to the vehicle owner that only a reserve supply of fuel is left and that it is necessary to replenish the fuel tank.

This object is accomplished in a simple and convenient manner and the invention further consists in the novel combination and arrangement of parts more fully hereinafter illustrated in the accompanying specification and drawings.

In the drawings:

Fig. 1 is a side elevation of the device forming the subject matter of this invention,

Fig. 2 is a vertical section therethrough, and r Fig. 3 is an end elevation.

Referring now more particularly to the drawings wherein like reference characters refer to like parts, it will be noted that there is provided'a casing 10 having an inlet opening 11 and an outlet opening 12. The device is adapted to be connected in the gasoline supply pipe and located between the tank and the carbureter.

Inasmuch as the casing 10 is elongated, its upper recessed portion 13 is arranged above the bottom of the tank. The upper end is hollow and is closed by a cap 1 1 screw-threaded therein. The lower end of the casing 10 is provided with a passageway 15 closed by a valve 16pactuated from the exterior bya handle 17 :or'thelike.

Extending upwardly from a passageway 18 formed in the casing'is-a threaded-pipe 19 and it will be obvious that by proper -ad-' justment the pipe 19 may be causedtoextend to varied extents upwardly into the recessed upper end 13 of the-casing 10. A second passageway 20 is formed in the casing 10 and connects the'recess l3 tothe passageway 15.

As mentioned 'hereinbefore, the device is inserted inthe gasoline supply pipe between the gas tank and the carbureter, with the upper recessed portion 13 arranged above the bottom of the tank. When the tank has a supply of gas therein and under normal conditions, this gasoline flows through the inlet end 11 up through passageway 20 until it rises to a sufficient level in the recess 13 to flow downwardly through pipe ,19, -pas-,

sageway 1-8 and on through the passage way 7 15 to the carbureter. Ob.viously,-in the normal working of the car thevalve 16 is closed as illustrated in Fig. 2.

The supply ofgas will therefore traverse this path on its way to the carbureter and gas Wlll. be furnished in the usual way until the amount has reached a level corresponding to the height of the pipe 19 as measured from a plane parallel with the bottom of the tank. That is, unless there is a sufficient supply in the tank to cause the gasoline to fill the chamber 13 and flow into the. pipe 19 the flow of gas to the carbureter will be stopped and to all intents and purposes the supply will be exhausted. However, by opening the valve 16 the straight conduit 15 will be made available and the remaining supply of gas in the tank will again flow into the carbureter. most cases be sufficient to enable the driver of the vehicle to reach a point where the supply of gasoline in the tank will be replenished.

From the foregoing it will be apparent that there is provided a simple and compact device which may readily and conveniently.

be used with gasoline supply tanks of motor vehicles and the like and which will prevent all of the gas under ordinary circumstances from being exhausted. The reserve amount maintained in the tank is however, easily available, but to make this supply available it is necessary to operate the valve 17 which acts as a positive warning to the owner of This amount will in the vehicle that the remaining available, supply of gas i limited.

Obviously, by making the pipe 19 adjustable vertically the amount of reserve gas maintained in thetank may be regulated. Furthermore the chamber or recess 13 acts as a sedimentation chamber in which particles of foreign matter will settle and be prevented from being carried to the carbureter and engine. By closing this chamber with the removable cap 14 the same may be conveniently cleaned.

While one embodiment of this invention is illustrated herein, it is not intended that the same be unnecessarily limited, but reservation is hereby made to make such changes in details of construction as may come within the purview of the accompanying claims.

Having thus described the invention, what is claimed is:

1. The combination with an automobile gasoline supply tank and pipe of a reserve supply device comprising a casing, said casing being formed with a recess adjacent its upper end and above the bottom of said supply tank, said casing being formed with a conduit adjacent its lower end and in alignment with said gasoline and supply tank, a valve in said passageway, said casing being formed with a pair of passageways arranged on either side of said valve and communicating with said first mentioned passageway and said recess, whereby when said valve is closed the gasoline will be caused to travel through said recess.

2. The combination with a gasoline tank and supply pipe of a reserve supply trapping device, said device comprising a casing adapted to be connected to saidsupply pipe and formed with a recess adjacent its upper end and above the bottom of said tank, said casing being formed with a passageway adjacent its lower end and in alignment with said supply pipe, a valve for controlling said passageway, said casing being arranged with vertically disposed passageways connecting said recess with said first mentioned passageway, a pipe adjustable to various heights disposed in one of said passageways and projecting into said recess, whereby gasoline to the level of said pipe. will be trapped in said supply tank when said. valve is in closed position.

3. The combination with a gasoline tank and supply pipe of a reserve supply trapping device, said device comprising a casing adapted to be connected'to said supply pipe and formed with a recess adjacent its upper end and above the bottom of said tank, said casing being formed with a pas sageway adjacent its lower end and in alignment with said supply pipe, a valve for controlling said passageway, said casing being arranged with vertically disposed passageways connecting said recess with said first mentioned passageway, a pipe adjustable to various heights disposed in one of said passageways and projecting into said recess, whereby gasoline to the level of said pipe will be trapped in said supply tank when said valve is in closed position, said recess being open at one side and a removable cap closing said recess.

In testimony whereof, I aflix my signature.
